IntroductionLittle is known about the pattern and outcome of Acute Kidney injury (AKI) in Sudan. This study aimed to determine the etiology and outcome of AKI among Sudanese adults.MethodsA retrospective cohort study was conducted in a tertiary level hospital, Soba University Hospital, Sudan. The medical records of all adults admitted to hospital from the 1st of January to 31st of December 2014 were reviewed. The diagnosis and severity of AKI was defined as per the Kidney Disease Improving Global Outcomes (KDIGO) recommendations.ResultsThe medical records of 6769 patients were reviewed. AKI was diagnosed in 384 patients (5.7%); being community acquired in 82.6% of cases. Sepsis, volume depletion, obstructive uropathy, heart failure, acute glomerulonephritis and severe malaria were the commonest causes of AKI diagnosed in 44%, 38.5%, 8.9%, 5.7%, 4.7% and 3.1% of patients, respectively. Following treatment complete renal recovery was seen in 35.7% of patients; whereas 31.2% of patients died. Predictors of increased risk of death were old age [OR 1.03, 95% CI (1.01-1.057); P=0.003], presence of chronic liver disease [OR 2.877, 95% CI (1.5-5.5); P=0.001], sepsis [OR 2.51, 95% CI (1.912-4.493);P=0.002] and the severity of AKI [OR 3.873, 95% CI(1.498-10.013);P=0.005].ConclusionAKI was diagnosed in 5.7% of adults admitted to hospital. Most patients were having community acquired AKI. Old age, the presence of chronic liver disease, sepsis, and the severity of AKI as per KDIQO staging were significant predictors of mortality.
IntroductionIn Africa and Asia hair dye is applied together with henna to decorate the hands and feet. Paraphenylene-diamine (PPD), a highly toxic constituent of hair dye can lead to acute kidney injury (AKI).MethodsA cohort study was conducted during the period from April 2012 to March 2013 in Khartoum Teaching Hospital, Sudan. It targeted adults presenting acutely with an evident history and clinical features of hair dye poisoning, together with AKI as per the RIFLE criteria. Analysis of data was done using SPSS.Results30 adults were included, their mean age was 25.6 ± 4.2 years, 93.3% were females. Exposure to PPD was suicidal in 86.7%. The mean duration to onset of renal symptoms was 34.8 ± 7.6 hours, maximum median serum creatinine was 8.6 ± 2.3 mg/dl, 86.7% had loss of kidney function as per the RIFLE classification and required dialysis. Initial renal recovery was seen after a mean duration of 9.8 ± 2.2 days. One patient died, 3.3%; all others, 96.7%, recovered normal kidney function. The amount of ingested PPD correlated significantly to the severity of symptoms, number of dialysis sessions required and time for renal recovery with P values < 0.05.ConclusionHair dye poisoning was associated with prolonged hospital stay, requirement of dialysis and increased morbidity. The severity of symptoms directly correlates to the dose of PPD ingested, with the kidney damage being reversible in almost all survivors.
IntroductionLimited data is available regarding the clinical manifestations and pattern of Systemic Lupus Erythematosus (SLE) in Sudan. This study aimed to determine the clinical manifestations and Antinuclear Antibodies (ANA) profile among Sudanese adults with SLE and lupus nephritis (LN).MethodsA descriptive study was conducted in Omdurman Military Hospital, Sudan. It included all adults with SLE and on regular follow-up during the study period (December 2012 to May 2013). These were investigated regarding their demographic details, clinical features, and immunological profile (ANA, anti-double stranded DNA, and ANA profile 3 levels). Patients with LN had their pattern of renal involvement described; furthermore, associations between the various SLE reactive antibodies and the histological diagnosis of lupus were studied.ResultsSixty-two Sudanese adults with SLE were included, their mean age was 31 ± 10.9 year. Females made 93.5% of patients. A clear predominance of those of Arab ancestry was seen, with most patients being from the Ja'alin and Shaigiya ethnic groups accounting for 29% and 12.9%, respectively. Arthritis was the dominant clinical manifestation seen in 85.5%, whereas renal involvement was seen in 66.1% of patients. Lupus nephritis class III was the dominant histological lesion, seen in 39% of patients. On correlating the ANA profile to the histopathological diagnosis of LN, anti-Nucleosomes and anti-AMA-M2 autoantibodies were found to be significantly associated with LN class IV and class VI, respectively (P values < 0.05).ConclusionFurther epidemiological studies regarding SLE and its ANA profile remain essential as they might help predicting the clinical patterns of the disease and its prognosis.
In Sudan, like most developing countries, the incidence and histologic patterns of primary glomerulonephritis (GN) remains undetermined. A cross-sectional hospital-based prospective study was performed to determine the pattern of primary GN among adult Sudanese patients. The study was conducted at Khartoum Teaching Hospital from September 2010 to August 2011. It included all adult patients with suspected primary glomerular disease and who underwent native kidney biopsy. A total of 83 adult patients were biopsied with 71 patients (85.5%) being diagnosed as having primary GN. Among those with primary GN the mean age was 34.6 ± 18 years and males represent 54.9%. In 46.5% kidney biopsy was indicated by the presence of nephrotic syndrome, whereas in 33.8% biopsies were performed due to unexplained elevations in renal parameters. Primary focal segmental glomerulosclerosis (FSGS) was diagnosed in 29.6% of patients, followed by membrano-proliferative glomerulonephritis (MPGN) in 26.8% and minimal change disease in 16.9%. IgA nephropathy was observed in 5.6%. Complications following kidney biopsies were reported in 9.6% of biopsied patients. Nephrotic syndrome in an adult was the most common indication for kidney biopsy in our unit. A large number of patients were biopsied due to elevated renal parameters, which reflected the increasing awareness toward thoroughly diagnosing patients with suspected reversible kidney damage. In conclusion, FSGS and MPGN make the most common causes of primary GN among Sudanese adults. Creation of a national renal registry is essential for obtaining more specified epidemiological data.
Thirty adult patients with cerebral malaria (CM) were recruited for this study. Two clinical groups were used as controls: those with mild malaria (n = 20) and asymptomatic volunteers (n = 20). Thick and thin blood smears were examined for detection of Plasmodium falciparum and estimating infection intensity. A nested polymerase chain reaction (PCR) using allele-specific primers for merozoite surface protein gene was used to determine the parasite diversity of Plasmodium falciparum causing CM. Plasmodium falciparum was detected in blood smears of all malaria patients. No significant difference in parasite count was found between the groups. Thirteen (65%) of the asymptomatic volunteers had a positive PCR for P. falciparum. Multiple alleles were found in 17 (58.6%) patients with CM, but only in 7 (35.6%) with uncomplicated malaria. Multiple alleles were also found in 6 (46.2%) of the 13 PCR-positive asymptomatic individuals. We could not identify a specific strain or strains of P. falciparum that showed a significant association with disease severity. Therefore, we assume that the development of CM in adults residing in endemic areas is more dependent on strain multiplicity rather than on a specific strain or strains of P. falciparum, and that the parasite intensity has no relationship with disease severity. Asymptomatic adults may repeatedly be exposed to low levels of a wide range of different strains during low transmission season and acquire sub-patent parasitemia. This may also confer premunition that renders them relatively resistant to CM.
